On January 12, 2010, the Toxicological Review of Methanol and the charge to external peer reviewers were released for external peer review and public comment. The Toxicological Review and charge were reviewed internally by EPA and by other federal agencies and White House Offices before public release. In the new IRIS process, introduced by the EPA Administrator, all written comments on IRIS assessments submitted by other federal agencies and White House Offices will be made publicly available. Accordingly, interagency comments and the interagency science consultation draft of the IRIS Toxicological Review of Methanol and the charge to external peer reviewers are posted on this site.

Status
Following external peer review the assessment will be revised taking into consideration external peer review and public comments, will undergo a final EPA internal review and a review by a science discussion with other federal agencies and White House offices, then will be posted to the IRIS Web site.
Methanol is a high production volume chemical with many commercial uses. It is a basic building block for numerous chemicals. Many of its derivatives are used in the construction, housing or automotive industries. Consumer products that contain methanol include varnishes, shellacs, paints, windshield washer fluid, antifreeze, adhesives, deicers, and Sterno heaters. This draft IRIS health assessment addresses both non-cancer and cancer human health effects that may result from chronic exposure to this chemical. This draft assessment provides an inhalation reference concentration (RfC) for chronic non-cancer health effects, a cancer assessment, and a reassessment of the oral reference dose (RfD). This is the first RfC and cancer assessment for methanol.
